Causes of watermelons and their solutions

In the process of watermelon growth, there will be a kind of physiological disease of watermelon, which seriously affects the yield of watermelon, and may even cause no harvest and bring huge economic losses to farmers. So what is the reason why watermelons turn into melons? How to solve it? Let's take a look at the detailed introduction.

1. Symptoms of melons

Chemical melon refers to the phenomenon that watermelons do not see long melons for a long time when they are cultivated, which is specifically manifested as the yellowing and softening of young melons after flowering. Although some melons seem to have been sitting on melons, they will melt away in a short time. Some show the phenomenon of growing at the top and melting at the bottom, and some do not grow directly. Melons have a great impact on the yield of watermelons, the young melons with flowers stop growing, the surface will turn brown, and the young melons will shrink until they dry up and fall off.

2. The cause

Encounter a long-term overcast and rainy climate at flowering stage, resulting in abnormal metabolism of watermelon, unable to pollinate and fertilize normally. In addition, in a high humidity environment, the fruit setting rate of watermelon is low; improper fertilization during fertilization leads to excessive vegetative growth of watermelon, affecting reproductive growth, and causing it not to sit melon, the same is true when watering. Improper watering time will also lead to watermelon not sitting. Pruning failed for pruning technology, resulting in a seedling to produce 5, 6 branches, or even more branches, these branches vary in strength, competing for water and fertilizer between batches, poor permeability, resulting in melons. In addition, in the prevention and control of diseases and insect pests is not timely, it will also lead to melons, such as Fusarium wilt, aphids, red spiders and so on.

3. Solution

First of all, according to different varieties, choose the appropriate sowing time, and choose sandy loam with good permeability as far as possible to avoid low-lying land so as to avoid the harm of stagnant water. Fertilization should be carried out according to the growth status of seedlings, especially to control the use of nitrogen fertilizer, in the land with better fertility, there should be less nitrogen fertilizer, so as to avoid excessive application of nitrogen fertilizer. Watermelon in the germination stage and seedling stage did not encounter special circumstances, should not be watered, watering once in the vine period, water is more important in the fruit-setting period, drought watering a small water, otherwise do not water, in order to avoid melons. Pruning should be timely, according to different varieties to take single vines, double vines, three vines and other pruning methods, the prevention and control of diseases and insect pests should be timely, but in the use of pesticides should not be too strong, spray it is best to avoid flowering.
